Toyota 4Runner V8 Y-Pipe (2003-2009 4th Gen): 304 Stainless, TIG-Welded

introducing the Toyota 4runner Y-Pipe: an exceptional upgrade crafted with meticulous attention to detail and utilizing premium materials. Our y-pipe is meticulously designed to enhance performance, optimize exhaust flow, and withstand the test of time. Engineered for seamless integration into the stock location, it ensures a perfect fit, eliminating the need for any modifications.

Crafted from high-grade 304 stainless steel, our y-pipe boasts 2.5-inch tubing, meticulously TIG welded and back purged to guarantee exceptional strength and durability. The inclusion of 3/8-inch thick flanges serves to prevent warping, ensuring a precise and reliable seal. Additionally, the flanges feature a unique rotatable design, accommodating the varying configurations of different years' 4runner models.

To provide added convenience during installation, our y-pipe incorporates four tabs strategically positioned at the center of the flange. These tabs enable easy alignment and secure positioning of your gasket, ensuring a consistent and reliable seal every time.

In response to customer demands, we have made significant enhancements to our design. The y-pipe has been expertly redesigned to extend beyond the transmission, allowing for seamless compatibility with skid plates. Furthermore, we have included a slip joint connection, simplifying the installation process and ensuring a hassle-free experience for our customers.

We proudly offer two distinct options to cater to individual preferences. For those seeking a harmonious balance between performance and acoustics, we offer a resonated option. This variant integrates StainlessBros 2.5-inch, 12-inch long resonators to reduce unwanted drone and enhance the overall auditory experience. For customers prioritizing emissions, we present the G-Sport catalytic converter option, available in non-EPA and EPA-approved versions.

Our esteemed 4runner Y-Pipe does not come with new gaskets included. We recommend utilizing the stock gaskets for a seamless fit and optimal performance. Should replacement gaskets be required, we advise procuring them separately to ensure compatibility with your specific vehicle model. By offering the y-pipe without gaskets, we allow our customers the flexibility to choose gaskets that meet their individual preferences and requirements.
